Description of the Related Art In recent years, a Pb-Ca-Sn-based alloy has been used for a grid body of an electrode plate for the purpose of maintenance-free lead storage batteries. In addition, Pb-Sb is used as an additional lead for forming a strap connecting the ears of the lattice body.
A system alloy is used. And the Pb-Ca-S
The ears of the lattice body using an n-based alloy and the additional lead for forming a strap using the Pb-Sb-based alloy are welded as follows to form a strap.
